Abstract
The propulsion system for the acceleration of projectiles is based on nitrocellulose and contains a crystalline energy carrier on a nitramine base and an inert plasticizing additive. The nitramine compound contains a structural element of the general chemical structure formula R—N—NO, where R is a residual. The nitramine compound is present in a concentration in the range from 1 to 35% by weight, in particular in the range from 5 to 25% by weight. The nitramine compound is preferably RDX. The inert plasticizing additive is a water-insoluble polyoxo compound, if necessary in combination with a substance containing carboxyl groups. In layers near the surface an increased concentration can be present. The inert plasticizing additive is present in a concentration of 1 to 5% by weight.
